My spare offering for you takes an old English proverb, "It's money for old rope", which means that you bought that cheaply, but where does this saying come from.
Well many centuries ago when someone was sentenced to death by hanging, the hangman used to get the old rope after the deed and sell bits off to the crowds that throng for the hanging, hence it was said that the hangman got money for old rope.
Sorry if that was gruesome. Best viewed with the magnify button above the pic.
